AUGUST NORDEEN, OF CONNERSVILLE, INDIANA, ASSIGNOR, BY MESNE ASSIGNMENTS,

'IO LAWRENCE MAXWELL, ,OF CINCINNATL/OHIO.

To an whom it may concern: r

Be it known that '1, AUG ST NQRDEEN, a

citizen of the United States residing at Connersville,- in the county'of Fayette and State of Indiana, have invented a new and useful Sectional-Accenting Device, of

the following is a specification.

This invention relates to that class of mu which sical instruments in which the playing is controlled by a music sheet passing overa tracker or Oth'enequiValent device.

.The 'principal'objects of the invention 'are' to provide simple :and effective means for permitting the instrument to be playedwith a loud'tone in any section or sections thereof, thus giving a solo effect, and especially to provide it-in such form that it can be controlled automatically from the music sheet through extra tracker 'ducts or can be con- 'tr'olled'at the lwill of the operator whether he is using a=mu sic sheet especially perforated for' this purpose or' otherwise. In other words, the'operator can control the'soloeffeet byhand alone or he can allow the paper to control it or if he desires, while it is unj der the: control of the paper, he can vary 1 and"of elongated"'-formsdthaflthey' remain Each one' is 'showh as the solo'efiect to suit his own ideas as to the playing of the music. In addition to'this the invention involves exceedingly'j simple and practical means whereby the'instru ment can be left in normal condition with the sectional hammer rest rail retracted from the strings'so" that the entire"instrument can be played with full loud tones and can be'operated manually without'restriction. Also the instrument can be left in such condition that the whole range of playing will be softened uniformly. K r

T he invention involves other improvements in details of construction and,combij nations as willappear hereinafter. v

Reference" is tobe had to the accompanying drawings in which Figure l is a front elevation of a portion of the action ofa pneumatic musical instrumentfconstructed in accordance with this invention. Figfl2- is a" fragmentaryfront elevation showing the indicator on the bottom of the tracker box and certain connections thereof; Fig.3 is a plan of the indi eating arrangement and other elements with" the upperpart removed and fthe'side' of the tracker box shown in section; Fig. 4 isfa' plan of the bottom plate of the parts shown in Fig. 3 withthe elements above it "re- I Specification of Letters Patent.
